Frequently Asked Questions

This is electric current in which the direction of flow is reversed at frequent intervals .It is usually at 230V from household sockets.
Theoretically, photovoltaic systems could satisfy power demands of country and even the whole world. Due to the fact that the sun doesn’t shine every day and at night, one would require storage systems. No serious company can however claim that photovoltaic is the only solution to energy problems worldwide. Instead, it’s true that solar energy in form of photovoltaic and solar thermal power used in combination with other renewable energy sources (wind, geothermal, hydropower, biogas etc.) would lead to electrical power supply methods that are not only sustainable but also which go easy on resources.
This happens when the shadow of a nearby object is cast onto a part of a solar generator. This often leads to a reduction in performance of the PV plant.
Solar energy is energy from the sun radiation which can be used chemically and/or in the form of warmth and electricity. Physically, it is electromagnetic radiation from the sun-surface. Compared to energy sources from fossils e.g. oil, gas, coal and especially uranium, solar energy is nearly endless as the sun will continue to exist for the next billion years.
How is energy from the sun converted to electricity using photovoltaic? Photovoltaics use photoelectric effect to convert energy from the sun into electricity. Two semiconductor materials with different charge carriers are inserted in the photovoltaic cells and separated by a membrane. The electrons are separated from the semiconductors with the help of photons in the sun radiation. The electrons then flow through the membrane to the other semiconductor –flow of electric current!
These are devices that conduct alternating current electricity into direct current electricity.
This term refers to the point at which performance is at its highest.
For optimum yield of module performance, the power inverter or solar charge controller must continuously adjust the voltage (V) so that the modules attain their MPP.
Energy utilized per unit of time.
The term used to refer to the direct conversion of light into electric energy.
